A method for precision forming by continuous free bending starts with establishing a correlation equation of a continuous axis f(x) to a bending radius R and determining a bending radius R at a real-time location in the axis. Based on the free bending technique, the method further involves establishing a correlation model of a real-time bending radius R of a tube to an eccentric distance U of a bending die and hence correlations of the equation of the axis to free bending parameters, and constructing a complete correlation model among f(x), R, U, and t based on a relational equation of an eccentric distance U to movement time t of the bending die to enable the precision forming of a complex component by continuous bending. Accordingly, the production efficiency can be improved.

The present disclosure provides a cleaning and recovery method and device for a heterogeneous executor in a mimic switch, and a mimic switch, the method includes: a mimic scheduler determining a designated heterogeneous executor that needs to be cleaned, marking the designated heterogeneous executor that needs to be cleaned as in a cleaning state, and sending a cleaning instruction to the designated heterogeneous executor; the designated heterogeneous executor sending a normal protocol negotiation message to the mimic scheduler to try to interact with the mimic scheduler; the mimic scheduler receiving the protocol negotiation message and detecting whether the designated heterogeneous executor is in the cleaning state; if in the cleaning state, the mimic scheduler constructing a training message, and sending the training message to the designated heterogeneous executor for protocol training; repeating sending and processing the protocol negotiation message until the designated heterogeneous executor is in a normal state.
